'bandage' originates from Old French, specifically the word 'bander' (to bind), with the suffix '-age' forming a noun meaning an act or result of binding.

'bandage' changed from the Old French word 'bandage' (from 'bander') into Middle English as 'bandage' and eventually became the modern English word 'bandage'.

Initially, it meant 'the act of binding', but over time it evolved into its current meanings of 'a strip of cloth used to bind or protect a wound' and 'to bind a wound'.
